Thanks for splitting the set.  0001 and 0002 are the minimum set for
back-patching, and it would be better to merge them together.  0003 is
debatable and not an actual bug fix, so I would refrain from doing a
backpatch.  It does not seem that there is a strong consensus in favor
of 0003 either.

Thomas, are you planning to look at this patch set?
